Answer:

3°

Step-by-step explanation:

Factor 5v^2 - 23v - 10​
AfilCa [17]

Answer:

(5v + 2)(v - 5)

Step-by-step explanation:

Hello!

The expression is written in the form of ax^2 + bx + c

Let's factor by grouping:

ac  = -50

The sum of the factors of -50 should add up to -23.

-25 and 2 work for this.

Expand and factor:

  • 5v^2 - 23v - 10
  • 5v^2 - 25v + 2v - 10
  • 5v(v - 5) +2(v -5 )
  • (5v + 2)(v - 5)

The factored expression is (5v + 2)(v - 5)

which expression below gives the average rate of change of the function h(x)= 4^x+2 on the interval -2 x 2
Drupady [299]
I believe your interval is [-2,2]:  all numbers between -2 and +2.

Then the ave. r. of c. on this interval is:

f(2) - f(-2)      4^2 + 2 - {4^(-2) + 2}
------------- = ------------------------------
  2 - (-2)                      4

                       16 - (1/16)            15 15/16
                 = --------------------- = --------------- = 3.98 or 255/64
                                4                        4
